48c0ea14c6 Remove PSA_KEY_TYPE_IS_RAW_BYTES from crypto.h 
It isn't used to define other macros and it doesn't seem that useful
for users. Remove it, we can reintroduce it if needed.

Define a similar function key_type_is_raw_bytes in the implementation
with a clear semantics: it's a key that's represented as a struct
raw_data.

4e69d7a9a7 psa_generate_key: pass parameters_size argument 
When calling psa_generate_key, pass the size of the parameters buffer
explicitly. This makes calls more verbose but less error-prone. This
also has the benefit that in an implementation with separation, the
frontend knows how many bytes to send to the backend without needing
to know about each key type.

e1fed0de18 Define elliptic curve identifiers from TLS 
Instead of rolling our own list of elliptic curve identifiers, use one
from somewhere. Pick TLS because it's the right size (16 bits) and
it's as good as any.
